PLANT FOR COOLING, REMOVING SCALE FROM, CH AL-KING, AND DRYING WIRE DELIVERED BY FINISHING-ROLLS.

Specification of Letters Patent.

. Patented Sept. 7, 1915.

7 To all whom it may concern Removing Scale from, Chalking, and Dry- Be it known that I, HEINRICH SCHLIGGE- MANN, engineer, citizen of the German Empire, residing at Gleiwitz, in the Province of- Silesia, Kingdom of Prussia, and Empire of Germany, have invented certain new and useful Improvements in Plants for Cooling,

ing Wire Delivered by Finishing-Rolls, of

which thefollowing is a specification.

In the wire industry it is well known to reel, remove as much scale as possible from, pickle, chalk and dry the wire coming from the finishing rolls in continuous succession, the wire being gradually cooled.

A primary object of this invention is to provide an improved plant for performing these operations, and the principal feature of the improved plant is that the reeling chamber is located remote from and elevated high above the finishing-rolls, a long tube being provided for guiding the wire from the finishing rolls to the reeling chamber, and friction rolls being preferably provided in the tube, whereas all or most of the individual devices associated with .the reeling chamber for the subsequent treatment of the wire are arrangedstepwise lower down.

The invention also consists in the peculiar and improved construction of the individual devices beyond the reeling chamber, and in the provision of the same with improved conveyer means.

Owing to the reeling chamber being located away from the finishing rolls and to its being elevated I attain the important advantages, as compared with plants known heretofore, that the wire is more severely cooled on its long way to the reeling device and at the end of its treatment is located close above the ground, whereas the coiled rings of wire heretofore had to be lifted by expensive lifting gear into the various de vices for subsequent treatment arranged stepwise at difl'erent elevations, and at the end of the treatment were'located higha above the ground if the first of the devices was not placed deep in the ground. Heretofore the said devices for the subsequent treatment of the wire could have been placed stepwise at a lower elevation only if the same had been arranged deep below the ground and had been provided with lifting gear at the end;

, rise.

To these ends the invention consists in the COIlSlJI'HCfilOIl, arrangement and combination ings, wherein F lgure 1 is a side elevation showing the finishing rolls, the friction rolls and the guide tube between the same, Fig. 2 is a longitudinal section through the .entire apparatus, Figs. 3 to 5 are cross-sections taken. through the scale-removing chamber, and

Figs. 6 to 8 are cross-sections taken through the pickling tank.

Referring to the drawing, in order to conduct the wire into the reeling chamber 0 located, according to the invention, at a distance from and elevated abovethe finishing rolls'a, I arrange friction rolls B in front of the feed tube 6 of the reeling device C and I guide the wire to these rolls B and from them to the feed tube 6 by a tube A having one end placed in known manner adjacent to the finishing rolls a. After the wire has been wound in 'lmown manner around the reeling device C the prongs of the latter passing through an inclined plane D are lowered and the ringof wire slides down the plane into the chamber F which, like the entire reeling chamber, isfilled with steam or any other suitable neutral or indifierent gasin order to diminish the formation of scale. The wire rings are conveyed in the chamber F by the bar G which is driven up and down and forward and backward by cam-driven lever mechanism f.

In Fig. 3 the bar is shown located in its middle position from which it is about to In Fig. 4: the bar has risen together with the wire ring, and will be moved forward. At the end of that movement the bar is downin the position shown in Fig. 5, wherein the wire ring, after having been moved forward together with the bar, rests on the side supports S. The bar is then drawn backward and lifted and the operation can be repeated. The wire ring is intermittently driven forward in this manner and finally slides under the door H into the pickling tank. J. The wire rings are conveyed in this tank in the same manner as in the chamber F, except that instead of the movable bar G a fiXed middle member K is provided, and instead of the fixed sidesupports S tw o movable side 'members. L are. em-

ployed.

In Fig. 6 the side members L driven by camdriven mechanism j are shown in the middle position from which they are about to rise.

In Fig. 7 the side members and the wire ring have risen and are pushed forward until at the end of that movement the side members descend to their lowest position (show'nin Fig. 8), wherein the wire ring,

ait'terhaving been pushed forward together with the-side members, rests on the middle;

m'ember K. '.The side members L are then drawn backward and the operation can be repeated. As soon as a wire ring is pushed intermittently forward in the manner described so far upon the middle member K that it no longer rests thereon, it will slide down into the trough M, and the latter is.

I lifted so-that the wirering then slides down larly conveyed by the trough chalking tank 0 and by .the trough M" into the tank N. The wire rin s are simiinto the (Fig. 2) onto the chain conveyer P which conveys thewire ring chalked in the hot milk-of-lime through the drying tube Q, in which the fan R produces a' violent movement of the air, whereby the wire ring leaves the chain conveyer dry and can fall into a wagon.

I claim removing scale from, chalking and drying wire delivered by finishing rolls of said mill, a reeling device which is located far away'from and elevated above the finishing rolls, a relatively long guide tube provided with friction shifting rolls therein arranged rolls, a relatively long guide t be provided with shifting 7 rollstherein arranged in front ofthe reeling device, and devices for subsequently treating" the wire after it has left the reeling chamber, said devices being partly located successively stepwise downwardly from said finishing rolls.

In testimony whereof I hereunto aflix my signature in-the presence of two witnesses. HEINRICH SCHLIGGEMANN. Witnesses:
